In 1980, Mt. St. Helen's erupted and covered the neighboring forest area with lava. In 1988, a fire burned down forested areas in Yellowstone National Park. Consider each site after the devastating event and how the living things at the two locations will change over time.

— Identify and explain two ways in which each succession in these two areas after these events would be alike and two ways in which they would be different.

The trp operon in e.coli regulates genes that code for enzymes required for synthesis of the repressible operon. when tryptophan is not available amino acid tryptophan. the trp operon is a in the environment, the trp repressor protein activeinactiveregulated. therefore, rna polymerase can bind to the genes to begin transcription.

The sketch shows a rynchosaur, an extinct animal that is known only from fossils. there has been much debate about the classification of these creatures. some scientists suggest that they belong with primitive amphibians, and some think they are related to snakes and lizards.the data equally support both cases. which statement best explains how to draw a cladogram that includes the rynchosaur? draw the cladogram for amphibians. draw the cladogram for reptiles. draw two cladograms, both showing the traits, and leave it as a hypothesis. draw two cladograms, both showing the traits, and have scientists vote

Which could be a pathway of food through an ecosystem
